ABBADAN'I.

Application filed October 17,1980. Serial No. 489,245.

which is used to a flattemng operation by passing it between pressure rollers and thereafter'to the action of a coiling mechanism in order-to impart to the wire an inherent tendency to curl. It has heretofore been customary in passing the wire through the coiling mechanism to form continuous coils.

It is the purpose of the present invention to have the coils intermittent instead of continuous, the coils being connected by substantially uncurled stretches of wire. The distance between the coils may vary in practice and such coils may be spaced any desired distance apart to give the desired results when the coiled wire is tangled into a bunch adapt: ed to be grasped by the hand of the user.

With the above and other objects in view, as will hereinafter fully appear, my invention comprehends a novel abradant.

It further comprehends a novel abradant in which coiled portions of the wire are connected by substantially uncoiled portions of wire.

Other novel features of construction and advanta'ge will hereinafter more clearly appear in the detailed description and the appended claims.

Figure l is a. view of an abradant embodying my invention which has been formed into a bunch.

Figures 2, 3 and 4 represent,-respectively, strands of wire in which the coils are space by substantially straight stretches or uncoiled portions of wire.

Similar numerals of reference indicate cor-- responding parts.

Referring to the drawing It will be seen from'Figure 2 that the wire 1 is formed with the spaced coils 2 which are connected by the substantially straight stretches of wire 3 so that straight stretches d coiled portions connected while in Figure 4 a much longer stretch 6 is shown as connecting the coils 7 and 8.

It will thus be apparent that the spacing between the coils may vary in accordance with conditions and requirements met with in practice. The wire is referably treated as described in the Sedigley Patent No.

1,777,900 patented October 7 1930, except that the coiling mechanism is so adjusted that the coils will be intermittent instead of continuous.

The wire is preferably passed through the flattenin rolls and thereafter during its travel it is subjected to an intermittent coiling action so that when the wire passes from the machine it has an inherent tendency to curl especially at the portion'at which the coils are present. y

In some cases it is not necessary to flatten the wire but the wire may be, irres ective of its shape in cross section, passed t rough a coiling mechanism which Wlll intermittently form coils in the wire during its travel. a

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is v 1. An abradant comprisin a flattened wire having coiled and uncoile portions alternately'throughout its length. 7

2. An abradant comprising a wire having spaced coiled portions connected by substantially straight stretches of wire.

3. A. fiexible and resilient metallic bunch comprising a metallic strand having spaced by substantially straight portions, with juxtaposed coils interlocking with each other.

In 3 the straight stretches of wire 4 which connect the coils 5 are shorter than l 5 the straight stretches 3,
